Ever since last year's U.S. presidential election race ended, the much-discussed concerns over Iran's nuclear build-up have vanished from the national debate. A sudden shroud over Iran, however, does not mean that the dispute is going to go away. The Iranian spectre will pop up again in unexpected ways.
If Israel believes it can set back the Iranian program substantially and if it perceives Western efforts to pressure Iran are not progressing fast enough to stop the Iranian program, Israel would be acting first to defend itself. But it also would be serving the interests of the Middle East, the U.S. and the wider world.
